 If there are any issues with connection with Openprovider, or for some reason API commands are not working, the first troubleshooting step should be to look at the API logs. Navigate to Utilities>Logs>Module Logs ​or <your WHMCS domain>/admin/systemmodulelog.php​ and you can find the raw API commands being sent and received by your WHMCS modules.
